In the chart above, is clearly shown that when using hardware acceleration, the total execution time of the AAC audio encode pipeline is significantly reduced. The average difference is 184.8 ms less in the pipeline execution time when the NEON&VFv4 extension is used. | In the chart above, is clearly shown that when using hardware acceleration (NEON&VFPv4 extension), the total execution time of the AAC audio encode pipeline is significantly reduced.

To measure this parameter, we used GstShark tool (developed by RidgeRun). | |||
In the chart above, it can be seen that when using hardware acceleration (NEON&VFPv4 extension), no reduction is achieved in the CPU workload. | |||
